White-throated Rockthrush Monticola gularis LT—no autumn records. WH—rare migrant at Beijing; first appearances in bird markets in three years 4-20 October. Sh—passing migrant and summer visitor. H—after return to Denmark, told of one caught 24 May 1946. COE—22 bird-days, 12-28 May. Ch—breeds at the Eastern Tombs, also noted as migrant and winter visitor to the province.
1986: a female or immature was at LH on 25 September.
1987: singles on 22nd and 30 September, seven on 8th and four on 9 October.
1988 (Ho): a juvenile male, 24 September.
1990: singles were recorded on 22nd and 25 September.
It seems this species is largely a spring migrant at Beidaihe, passing in May. Cheng’s assertion that it occurs in Hebei in winter is surely questionable.
Blue Rockthrush Monticola solitarius philippensis LT—not noticed in autumn; breeds in the mountains. H—two autumn records; by contrast, seen on 30 dates in spring. COE—50 bird-days, 30 April to 23 May.
1986: 56 bird-days, 20 August to 27 September. All records were from LH and birds were seen on most days during the period, usually one or two in a day. The highest day total was seven on 6th and 7 September; six were seen on 22 August.
1987: 61 bird-days, beginning of the survey to 7 October; highest day totals ten on 29th and eight on 30 August; only singles after 12 September.
1988 (Ho): at least three birds seen, 9-13 September.
1990: before 23 October, 23 bird-days, highest day totals three on 24th, 29th and five on 31 August. The only record after 23 October was a female or immature at ER on 30 October; late for this species.
Siberian Thrush Zoothera sibirica LT—passes in spring; no autumn records. WH—only records were in the food market, 23 May and 1 November 1919. H—three records in May. COE—14/15 individuals, 15-23 May.
1986: three were seen at Temple Gully, LH, on 11 September—a male, a female and an immature male.
1988 (Ho): a male seen from the LH watchpoint, 11 September; a thrush which was probably a female of this species was seen from the watchpoint on 24 September.
1990: two males on 1 September.
White’s Thrush (Scaly Thrush) Zoothera dauma LT—six autumn records in six years, 24 August to October. H—four or five birds in three autumns. COE—five seen, 7-15 May.
1986: 42 bird-days, 2 September to 9 October. On most days from 11 September one or two birds were seen, or occasionally three or four. The highest day total was five on 28 September; there was a slight cluster of records at this time. Seen at a variety of localities.
1987: 59 bird-days, 19 September to 21 October; 13 were recorded flying south on 12 October.
1988 (Ho): 15 bird-days, 9 September to 1 October.
1989: 12 bird-days, one to four recorded on six dates from 15-27 September; seven bird-days, 10-29 October; other than a late bird over 28-29 October—and a long-dead one on 9 November—five bird-days (two birds?), 10-14 October.
1990: eight bird-days, highest day total two on 23 September; all before 23 October.
Grey-backed Thrush Turdus hortulorum LT—no autumn records. H—one spring record. COE—singles on 1st and 14 May. Ch—migrant through Hebei.
1986: four were at YH on 30 September, one was at the same locality on 3rd and one at GS on 8 October.
1987: 56 bird-days, 27 September to 11 October; highest day totals of birds present were 30 on 7th and eight on 9 October; 15 flew south on 3 October.
1988 (Ho): one seen, 2 October.
1989: recorded on three days in October: one at Legation Gully on 17th, one at LH on 18th, and singles at LH, LP and Re on 27th.

Eye-browed Thrush Turdus obscurus LT—sparingly, 14-24 September. H—less common than spring, 10-16 September. COE—166 bird-days, 10-31 May.
1986: 65 bird-days, 2 September to 6 October. As with the White’s Thrush, the first record was not followed until 11 September (the same day as the only record of the Siberian Thrush). Thereafter, one to four birds were seen on most days, with a slight concentration of records from 22-27 September, when 27 bird-days were logged. The maximum count was 12 birds at LH (the favoured locality) on 27 September.
1987: 203 bird-days (79 were recorded flying south), 5 September to 12 October; highest day totals of birds present were 11 on 18th, 14 on 20th and 23 on 22 September, and of birds flying south, 19 on 21st and 17 on 22 September.
1988 (Ho): 60 bird-days, 9 September to 3 October; 30 bird-days 17-20 September.
1989: 18 bird-days, one to nine recorded on six dates, 15-28 September; singles were at TH on 9th and LH on 23 October.
1990: 51 bird-days, all before 23 October.
Red-throated Thrush Turdus ruficollis ruficollis LT—no autumn records. WH—fairly common in company with Dusky and Naumann’s Thrushes all winter; the ‘few records in the field and many in the market’ were all between 14 November and 21 March. Rare in northeast Hebei (Wilder and Hubbard 1938). H—no records. COE—four birds, 1 April to 1 May.
1986: a male was at YH on 7 October.
1987: three on 6th, two on 7th and 8th and one (flying south) on 18 October.
1988 (Ho): one seen, 3 October.
1989: four records—two females or first-winters (this sub-species or Black-throated Thrush T.f. atrogularis) at LH on 6th, a male at Re on 28 October and a female at the same locality the following day and one, probably female, at Study Gully on 16 November.
1990: two were seen on 22 September.
Dusky Thrush and Naumann’s Thrush (Rufous-tailed Thrush) Turdus naumanni eunomus and T. n. naumanni LT—the Naumann’s Thrush appears rather late in October and through November; winters in sheltered places on the plain. The Dusky Thrush passes in October. WH—on the plains the Naumann’s Thrush is a very common migrant and rare winter visitor; much more common in the hills in the winter. First records in autumn between 12 September and 20 October; pass on south or to the hills by 20 November. Dusky Thrush common, but much less so than Rufous-tailed; most common as a migrant. H—18 dates in three years from 1 October to 29 December; the Dusky Thrush returns earlier in autumn. COE—108 bird-days logged for the Dusky Thrush, main passage 9-19 April, last date 20 May; 228 bird-days logged for the Naumann’s Thrush, main passage 25 March to 5 April, last date 1 May.
1986: 1042 bird-days were logged for both subspecies (i.e. including birds racially identified), 24 September to the end of the survey. The main passage period was 8-14 October, when 315 bird-days were logged and the highest day count—136 birds—was made on 6th. Numbers were otherwise fairly evenly distributed throughout the period. In agreement with La Touche and Hemmingsen, we found that the Dusky Thrush passed earlier than the Naumann’s. with half of the 66 bird-days for this subspecies logged during the first two weeks of October. The main passage of the Rufous-tailed Thrush was about two weeks later, and 136 bird-days were logged in total. Four hundred and ten birds were logged from LH, flying south. Of these, eight were identified as Dusky and 35 as Naumann’s.
1987: 3289 bird-days (2784 flew south), 26 September to the end of the survey; 1950 were recorded flying south during the morning of 11 November; other notable totals of birds flying south were 275 on 13th and 230 on 30 October.
1988 (Ho): 337 bird-days, 25 September to the end of the survey.
1989: 1024 bird-days (874 flew south) were logged for Dusky Thrush/Naumann’s Thrush (i.e. of undetermined subspecies), 8 October to 10 November; highest day totals 440 (420 flew south) on 27 October and 283 (268 flew south) on 5 November. For the Dusky Thrush: one on 6 October; 288 bird-days, 8 October to 5 November; highest day total 148 (135 at Re) on 27 October. For Naumann’s Thrush: 49 bird-days, 19 October to 16 November; highest day total 17 on 27 October.
1990: for Dusky Thrush/Naumann’s Thrush: Before 23 October, 127 bird-days, highest day total 31 on 8th and 15 October. From 23 October, 160 bird-days (37 were recorded flying south); highest day total 63 (12 flying south) on 4 November. For Dusky Thrush: five on 23rd, six on 24 October, and one on 4 November. For Naumann’s Thrush: 200 bird-days (120 were recorded flying south), from 23 October to the end of the survey; highest day totals of birds flying south 34 on 26 October, 20 on 2nd and 65 on 3 November, and of birds present 17 on 31 October, 26 on 4th and 14 on 10 November.
•(NT)Chinese Song Thrush Turdus mupinensis LT, H, COE—no records. Ch—resident at Eastern Tombs, in Hebei. Breeds sparingly near Beijing (Cai 1987).
1989: one was at LP during 13-15 October.
1990: one was seen on 14 September.
Judging by recent spring observations, this thrush breeds at Old Peak, north of Qinhuangdao (MDW pers obs.).
Unidentified thrushes Turdus spp.
1986: 402 unidentified thrushes were recorded from 22 August to 11 November; 349 were recorded from LH, flying south, and the highest day count was 69 on 5 October. Most occurred late in the period, and it seems likely the records mainly involve Dusky or Naumann’s Thrushes.
1987: 108 bird-days, 27 September to 18 October.
1988 (Ho): 20 bird-days.
1990: 16 bird-days, before 23 October.
